TOKYO -- NTT DoCoMo Inc., Japan's largest mobile operator, is planning to fix a weakness in its service: When customers travel overseas to places like the U.S. and China, they can't use their phones unless they have a specialized model.

Masao Nakamura, DoCoMo's chief executive officer, said in an interview that the company plans to add new global-roaming capabilities to its top line of cellphones, starting late this year.
